To all whom it may concern.:

Be it known that I, CHARLES A. FROST, a citizen of the United States,residing at Testern, in the county of Saline and State of Nebraska, haveinvented a new and useful Pump-Operating Mechanism, of which thefollowing is a specification.

My invention relates to *improvements in mechanism for operating pumps,the objects of which are to provide a 4mechanism which may be operatedby a windmill, or which can be adapted for use in house wells andcisterns; and with these main objects in view my invention consists incertain features of construction to be hereinafter described, and thenpointed out in the claims.

In the accompanying drawings, Figure 1 is a section taken through aweil, showing a pump in position in the same and my improved operatingmechanism in connection therewith. Fig. 2 is a detail view of the framefor supporting the operative parts. Fig. 3 is a detailviewof the linkconnecting the operating-crank with the piston-rod. Fig. 4 is a detailview of the clam p-couplin g for connecting the pump with a windmill.Fig. 5 is a vertical sectional view taken through the standard and thepump-rod.

1 is a well, above which is supported on the platform 2 the frame 3,which carries the operative parts.

4 is a tube that is sunk within the well and is provided at its lowerend with a head 5, provided with perforations to admit the water. At thetop of the tube is a cylinder 6, provided with upper and lower heads 8and 9, respectively. At the lower end of the cylinder is a nozzle 11, towhich is attached the tube 12 of spout 13, which projects above thewell, and the cylinder is supported in position within the well by meansof a rod or brace 14, the brace being secured to the cylinder at 15. Thepiston-rod, which is designated by 1G, is extended intothe pump-cylinderand carries a piston. (Not shown.) Suitable valves are likewise to beproperly arranged in the cylinder or in the inlet and exit tubes of thelatter, as will be readily understood 19 is a crankshaft journalcd inboxes 20, secured to frame 3 and provided with ahandcrank 21. The link 2is provided at its lower end with eyes 23, between which fits the eye 24at the upper end of the piston-rod 16, and through said eyes pivot-pin25 passes.

The upper end of said link or pitman 22 has y 'link is also provided atits outer end with a pin 36 on its inner face. As shown in Fig. 1 infull lines and in dotted lines in Fig. 2, said flap is brought up sothat its pin 3G will engage or take into perforation 37 above the recess29, thus providing a boxing for the crankshaft 19, which is receivedwithin the concavities 29 and 35, which together constitute a circularjournal. By constituting the boxing, as shown, with ahinged iiap, thelink may be separated very readily from the crank 19, the convex portion35 of said flap when thrown down, as shown in full lines in Fig. 3,being received bythe concavity 30. This manner of constructing the linkwith a two-part boxing enables the ready repair of the parts of thepump.

As above described, the pump maybe used in a house well or cistern, butmay' be readily adapted for use in connection with a windmill by theemployment of the device shown in Fig. 4. At the lower end of thepump-rod 38 of the windmill is a socket-piece or box consisting of twoparts 30 and 40, secured to the pump-rod by means of bolts 41 passedtherethrough. The lower ends of the parts 39 and 40 are provided,respectively, with hinged iiaps or links 42 and 43, said paired linksconstituting a clasp-coupling. The inner side of the lower end of link42 is provided with a pin 44, that is adapted to pass through the eye 2Gat the upper end of the pitman 22 and into a perforation 45 in the lowerend of the opposing link 43, thus coupling the pump to awindmill. Theouter end of the pin 44 is provided with a perforation IOC Li6 toreceive a suitable key. (Not shown.) Between the upper hinged ends ofthe paired links 42 and 43 is placed a spring 47, which is adapted whenthe Windmill is disconnected from the pump-the aforesaid key having beenremoved-to throw apart said links to allow room for the free movement ofthe pitman 22.

That I Claim is- 1. The combination, with a pitman having an eye at itsupper end, of paired flaps or links hinged at the lower end of avertically-reciprocating rod, one of said flaps carrying a pin adaptedto pass through the eye of said pitman and to enter a perforation in theother flap substantially as and for the purpose set fort 1.
